Stuff that shouldn't be in the oil - depending on what has happened to the transformer, different particulates will be found. Gasing, internal arcing, insulation degredation, etc. will have different "fingerprints", or patterns of molecules in the oil. Oil analysis can be used to identify Transformers that are at risk of failure in the near future.
Oil is used to cool the transformer. There is no telling what the transformer in question uses without knowing the specific part number and looking up the specification.
Transformer oil is pure insulating oil.
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
Nytro libra is an uninhibited transformer oil
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
transformer consists of polychlorinated biphenyls,...etc
As well as providing a cooling medium, transformer oil is also used to insulate a transformer. As its dielectric strength (how well it insulates) is much higher than air, it means that components within a transformer that are at different potentials can be placed much closer together if they are immersed in oil. So, operating an oil-filled transformer without oil will likely cause insulation breakdown within the transformer.
convection currents
it is a pit which is used to drain leakage oil of transformers .AnswerIt's a walled area, surrounding a transformer, intended to contain any oil leakage from a transformer.
minarel or power oil
Its "Mineral Oil".
The function of the radiator ban in a transformer is to cool the transformer oil.
